What should I pull up in Level 14?

Jump into the white square with the small handle above the gap; it activates the tree that raises the central platform.

When should I jump to the door?

Wait until the tree has lifted the center platform close to the right ledge, then jump right from the raised platform.

Activate the handled square, ride the tree-raised center platform, and jump from its new height to the right door.

Layout: A low left starting platform faces a gap and a lower central platform. A white handled square hangs above the gap, while the exit door sits on a tall platform at the far right.
Goal: Raise the central platform until it aligns with the right exit ledge, then enter the arched door.
Opening: Move right and jump into the handled white square to start the tree/platform lift.
Danger Zone: The central platform starts too low for the final jump; trying to cross before activation leaves the potato short of the right ledge.
Mechanics: Pulling the overhead handle grows a tree that raises the central platform and changes the route height.

The first jump is for the handle, not the door. Wait for the tree-supported platform to rise.
Launch the final jump only after the center platform is visibly near the height of the right ledge.
Think in chain clears. The best move is the one that sets up the next two moves, not just the quickest current match.

Move right on the left starting platform until the potato is directly below the white handled square.
Jump into the square to trigger the 'Pull it up!' interaction.
Land on the central platform as the flower/tree appears, and stay with it while it rises.
When the raised center platform lines up with the right ledge, move to its right edge.
Jump right onto the tall exit platform and enter the arched door to finish.

Jumping from the original low center position toward the door misses because the platform has not risen yet.
Leaving the central platform before the tree lift reaches exit height removes the only reliable launch point.
